NTVDM has encountered an illegal instruction
Within moments, whenever I log into IE6, I encounter a Blank DOS screen (16 bit MS DOS Subsystem). This is followed by an error message "NTVDM has encountered an illegal instruction, etc..... "
I can always get out of the problem with the cancel button. I have also noticed that if I leave IE
open for several hours, that the same message will come up again on a very exact timetable, as if though
there is a scheduled activity taking place. I have no scheduled activities in any of my applications.
I have taken the following steps to try and resolve the problem but have had no luck.
1. Ran a virus check 2. Ran Spy Sweeper 3. Reloaded IE6 4. Reduced "START UP" and "Services" to a bare minimum
The problem still continued I even installed Netscape 7 to try and isolate the problem. Netscape ran OK, however as soon as I get back to IE the problem comes up again. It is as if though IE is executing some background routine that is causing the problem. I do not want to reload XP (Pro) as that would wipe out my system. Help!!!

/SCANNOW Scans all protected system files immediately.
/SCANONCE Scans all protected system files once at the next boot.
/SCANBOOT Scans all protected system files at every boot.
/REVERT Return scan to default setting.
/PURGECACHE Purges the file cache.
/CACHESIZE=x Sets the file cache size.

I tried the recommendedations, however nothing seems to work, as the problem continues to be there.
The only thing i can conclude is that there is a 16 bit application tied to the first time IE is used. It does not matter what web site I start with, becuase the problem comes up within 30 seconds.
Will continue to work the problem, as the reload of W/XP is the very, very, very last option.

Are there any 16-bit browser extensions that serve a legitimate purpose any more? What happens if you disable third-party browser extensions (Advanced/Browsing under "Internet Options")?
Try checking the machine for spyware/malware using Ad-Aware and Spybot as described in this article.

Perhaps a clue.
In my \Windows\System32 directory I have the following executable in my Start Up. No matter what I do I can not get rid of them, and I can not find any reference about them at Microsoft.
KWARKC.Exe
Also, I get the following in my Start Up that points to my \ Documents and Setting\All Users\Start Menue\Programs\Startup\nhgtni.exe
I can not find any info on this as well.

The most frequent source of oddly-named executables is spyware/malware. I'd suggest checking your machine again. See my last post for information about obtaining Ad-Aware and Spybot.

I did run all of the applications that were recommended.
These 2 executables I found as I started to did into it deeper.
Now I'm down to the less obvious.

The less obvious ones tend to require expert help.
Download HijackThis, a malware analysis and removal tool, and submit the log it produces for analysis.
Here's an illustrated guide to installing and running HijackThis that you may find helpful.
Copy and paste the contents of the log you saved in a new message in the Virus/Spyware Information and Removal board. Be sure to describe the problem you're experiencing.
